hmmmm, seems to be as tricky as it appears?

hi everyone, I am getting unpredictable wxSOCKET_IOERR and struggle to get to the bottom of this. How can I get more information, i.e. was there a buffer problem? Which side of the TCP connection produced the error? Another thing: to reduce problems I started securing socket access by different thre...

I draw a rotated wxBitmap. Is there a function to calculate where on the rotated wxBitmap the mousePos is? Something to give the rotation parameters that transforms the position on screen to the position within the rotated bitmap? I think I have seen something like this a while ago but cannot find i...

WPF is Microsoft's (not only) GUI library for Windows, available from .NET. It allows applying various transformations incl. rotation to the controls but all the controls are custom-drawn by the library, it does not use the native Win32 controls. I just used WPF as a rare GUI example where the cont...

Aren't things like this usually done with custom drawing (including e.g. WPF controls with transforms) instead of using native windows? I did not read this properly the first time. What do you mean by "wpf controls"? My approach would be to calculate if the mouse is over a painted button area on th...

thank you for your tip! while starting to implement a mouse sensitive bitmap with all the button images on it, I realized there is a performance advantage compared to having a lot of single buttons. It could happen in my case that I need to create and display >100 and that takes a while with wxPanel...

I understand that no one wants to re-invent a wxButton. But assuming I was not wrong, what is the alternative?

Yeah, I guess this might be the only way. Bummer.

A custom drawing would be possible of course, but it would be quite an effort to incorporate button feeling with mouseover and cursor change to show the user that a certain area is clickable.

With the help of this wonderful forum I managed to draw rotated stuff on a wxGCDC, which is wonderful. Now I have custom wxPanel "buttons" to select parts of an image, in this case the arrow buttons can be clicked to select a row/column of circles: rotatePanel.jpg The image can be rotated, as seen h...

On MSW it works (the control is a generic one combining wxTextCtrl and wxSpinCtrl) but it may not work elsewhere.

That is okay, my program will always be limited to windows.
Really helpful answer, thank you! I also learned something new about how to use templates.

A little follow up question: Can I somehow put this in a class that a lot of different spin controls can inherit from? class DECLDIR_CONF spinCtrlBasis { public: spinCtrlBasis(int winId){ getEvtHandler()->Connect(winId, wxEVT_TEXT_ENTER, wxCommandEventHandler(spinCtrlBasis::onEnterKey)); getEvtHandl...

delayed using CallAfter

unfortunately it still does nothing.

void OnSpinCtrlTextEnter(wxCommandEvent& evt)
{
wxWindow* win = dynamic_cast<wxWindow*>(evt.GetEventObject());

win->Navigate();
}
};

YES! Thank you!

Without trying, i'd say: Catch wxEVT_TEXT_ENTER event and call Navigate() in the event handler.

That sounds perfect and was what I was looking for, unfortunately nothing happens.

I have it in a wxPanel.
Nothing happens when I press Enter.
wxWidgets 3.1.3 on Windows 10 Pro with Visual Studio v142 build tools (10.0.18362.0).

I have a wxSpinCtrl and want to leave the control when the user presses Enter, just like what happens when the user pressed Tab. The wxEVT_COMMAND_SPINCTRL_UPDATED should be triggered and the next control selected.
I am surprised that seems to be difficult. How can I achieve this?
